설계 모델을 이용한 UO2 펠릿 20 kg HM/batch용 분말화 장치 제작
Manufacture of the vol-oxidizer with a capacity of 20 kg HM/batch in UO2 pellets using a design model
Abstract
Vol-oxidizer is a device to convert pellets into powder and to feed a homogeneous powder into a Metal Conversion Reactor in the ACP(Advanced Spent Fuel Conditioning Process). In this paper, we propose a design model of the vol-oxidizer, develop the new vol-oxidizer with a capacity of 20 kg HM/batch in pellets, and conduct a verification for the device. Design considerations include the internal structure, the capacity, the heating position of the device, and the size. The dimensions of the new vol-oxidizer are decided by the design model. We determine a permeability test of the measuring the temperature distribution, and the volume of and . We manufactured the new vol-oxidizer for a 20 kg HM/batch in pellets, and then analyzed the characteristics of the powder for the verification. The experimental results show that the permeability of the throughout mesh enhance more than old vol-oxidizer, the oxidation time takes only 8 hours when compared with the 13 hours of the old device, and the average distribution of particle size is . The capacities of new vol-oxidizer for a 20 kg HM/batch in pellets were agree well with the predictions of design model.
